3.2 Job Driven Mode

Upon starting the Scanner prompts the user to choose the acquisition Options andthe scanning Strategy to use

Three Strategies are available:

Inplace: Standard strategy. The job stumps stay in the original position duringscanning. No realign is required

Multidie: Alternate strategy. The job stumps are positioned on a specialdevice. They need to be realigned manually later

Fast Coping: it is particularly useful when a single Stump has to be scanned

The below Options allows the user to add elements to scan:

Gum

Waxup

Antagonist

Workarea definition flag force the scanner to focus on a specific arc jaw areaavoiding to acquire the entire model saving computational time

50


3.2.1 Acquisition Workflow

Depending from the strategy and option selected, the Dscan sets several Steps inorder to acquire the arc jaw model and related stump in the best possible way. Thissets of Steps are called Acquisition Workflow. To help the user to navigate in theworkflow a wizard like UI is provided. There are three type of Steps used byscanner to make an Acquisition Workflow:

1. Scan Step: The model is scanned using several positions depending from thespecific Step. After a Finalize meshes are created. Obviously an arc jaw, a toothor other models have to be inserted in the scanner by the user

2. Registration Step: Meshes are aligned each other. The alignment requires toselect three points on a fixed mesh and the homologous ones on a movablemesh. The application compute the transformation in order to minimize thedistances. In order to align to mesh they have to have overlapping areas. It is notpossible to align meshes without overlapping

3. Assignement Step: Meshes are segmented and assigned to the appropriateteeth

For example below are listed the Steps to acquire a simple job using Inplacestrategy and Workarea flag on. No additional options selected

1. Workarea Definition

2. Total Model Acquisition

3. Neighbors

4. Inplace

5. Registration

6. Finish

The same Workflow adding Gum Option:

1. Workarea Definition

2. Total Gum Acquisition

3. Total Model Acquisition

4. Gum Registration

5. Gum

6. Neighbors



7. Inplace

8. Registration

9. Finish

In the following sections Steps are described in details

52


3.2.1.1 Workarea Definition

The Workarea Definition is a Scan Step. Ii has the goal to focus all the scanningand computation effort to a specific arc jaw area avoiding to acquire the entiremodel saving time

Workarea Definition

1. Quick acquisition, only 2 positions by default, of the total model is done. NoFinalize is required

2. Teeth segmentation and linking. When all the teeth are linked to a workarea, thestep is completed. In this step the top view is blocked, and only panning is



allowed.

54


3.2.1.2 Total Model Acquisition

The Total Model acquisition is a Scan Step. It is used for two purposes:

1. Neighbors and Pontic element definition

2. Reference for other acquisition Steps

Total Model Acquisition

1. Detailed acquisition, 8 positions by default, of the previously defined workarea.To finish the acquisition a Finalize is required

2. Upon completion of the acquisition it's possible to use the Fill Holes or Spike



removal tool to heal the mesh. When no further editing is needed, the step iscompleted

56


3.2.1.3 Neighbors

Neighbors is an Assignment Step. A manual segmentation is needed to identify allthe neighbors and pontic elements in the Total Model acquisition.

This step is usually performed using the polygon and the lasso selection tools.

Neighbors segmentation

1. Correct manual segmentation of the single meshes:

2. Linking of the segmented meshes to the preparation elements; pick thesegment and the arcjaw teeth by single click to link;



3. Correctly linked elements are shown in pale orange; unlinked elements areshown in bright orange. Once all elements have been correctly linked the step iscomplete.

58


3.2.1.4 Inplace

Inplace

The Inplace is a Scan Step. This strategy implies keeping the stumps on the base,while removing all the other elements. Stumps scanned this way are already in theright position, no additional step are required

If the preparation involves several stumps the scanner automatically could split theacquisition in two or more separate Steps

Inplace workflow

1. Acquire the stumps, 16 positions by default. A Finalize is required. Elementsscanned this way are already registered with the total acquisition:



2. Link the elements; pick the segment and the arcjaw teeth by single click to link

If one tooth is not well acquired don't assign it. Remove from the base the rightones and repeat the scan running it from pulldown menu. (The Scan button isinactive)

Dscan deletes automatically the not assigned mesh and repeat the acquisitioncycle

60


3.2.1.5 Multidie

Multidie

Multidie is a Scan Step. This strategy implies removing the stumps from the baseand inserting them into a special tablet, according to a specific pattern. Thestumps are scanned in a different position respect the arc jaw, an additionalregistration step is required and mandatory to move them in the right position. Asreference the Total Model is used

.

If the preparation involves more than five stumps the scanner automatically split theacquisition in two or more separate Steps

Multidie workflow

1. Acquire the multidie support, 16 positions by default. A Finalize is required tofinish. The meshes are assigned automatically by DScan if the flagAutoassignment is on



If one tooth is not well acquired deassign it clicking on the related arc jaw icon.Remove from the rotating tablet of the scanner the right ones, move just a little thewrong stump and repeat the scan running it from pulldown menu. (The Scan buttonis inactive). When the multidie scan dialog box appears unflag the Autoassignment. Dscan deletes automatically the not assigned mesh and repeat the acquisitioncycle

62


3.2.1.6 Registration

Registration has the goal to align meshes to other one. Usually stumps or waxup are aligned using Total Model. Registration Step is mandatory for stumps acquiredusing the Multidie approach, and optional for Inplace acquisition.

Registration

1. Click in the arc jaw on the tooth to register: A dialog box appears

2. Select three or more homologous points on both the single teeth and the totalmodel. At any time is possible to RESET the selection or ABORT the operation.Once done click the REGISTER button



3. By clicking the OK button the operation is completed. A successfully registeredelement is shown with a green label in the jaw view:

4. Repeat the step for each element to align

64


3.2.1.7 Finish

When all the Steps in the Acquisition Workflow are done, the scanning process iscomplete. The Scanner application is ready to move all the data acquired to theModeling Prosthesis phase. This is automatically done clicking on the NEXT button



3.2.1.8 Gum

When Gum option is checked the Scanner add three Steps to the AcquisitionWorkflow:

1. Total Gum Model Acquisition

2. Gum Registration

3. Gum Assignment

Total Gum Model Acquisition

Total Model with gum is acquired, 8 positions by default. A Finalize is required

Gum Registration

This Step is composed by two parts:

1. A not mandatory Registration of the two total model acquisitions

2. An semiautomatic segmentation. A specific tool for gum identification,

accessible via the button , is available. Using this tool and proper scannedtotal models, it's possible to isolate gum without the need of manualsegmentation

66


Gum Assignment

Segmented gums must be linked to the proper tooth



3.2.1.9 Waxup

When Waxup option is checked the Scanner add four Steps to the AcquisitionWorkflow:

1. Total Waxup Model Acquisition

2. Total Waxup Model Registration

3. Waxup Acquisition

4. Waxup Registration

The purpose of these Steps is to acquire shape to be used instead of the defaultones available from internal DentalCAD libraries. It means that some modeling jobhas to be performed to make the shape acquired compatible. This job is done inthe Waxup Acquisition Step mainly using Delete and Fill hole commands

Total Waxup Model Acquisition

Total Model with Waxup is acquired, 8 positions by default. A Finalize is required

Total Waxup Model Registration

A not mandatory Registration of the two total model acquisitions is available ifrequired

Waxup Acquisition

This Step is composed by two parts

68


1. The Waxup model is acquired, 5 positions by default. A Finalize is required.

2. Segmentation and element linking is then required. Waxup has to be preparedin order to substitute library elements. It means the Waxup bottom has to have aregular hole in order to be able to connect to the Margin Ring. To achieve thisresult some modeling jobs is required using Delete and Fill hole commands:

1. Delete the Waxup support



2. Split the total shape in single shapes cutting connectors if present

3. Recreate lateral faces using fill hole command

4. Delete the bottom of the waxup in order to create the base hole

70


Waxup Registration

A not mandatory Registration of Waxup shapes is available if required. Thereference model will be the Total Waxup Model



3.2.1.10 Antagonist

Antagonist

When Antagonists Option only is checked (no checkbite), the Scanner add threeSteps to the Acquisition Workflow:

1. Couple Model Acquisition

2. Antagonists Acquisition

3. Antagonists Registration

Couple Model Acquisition

Acquire the Couple Model. A quick acquisition, 6 positions by default, of both arcjaws, superior and inferior, is performed.

72


Antagonist Acquisition


1. The user is required to scan the full antagonists arc jaw, 8 positions by default.A Finalize is required

2. Segmentation and element linking is then required



Antagonist Registration

Perform the registration between the antagonist jaw and the Model Couple bypicking the contact points. Once all elements have been correctly registered thestep is complete.

Checkbite

74


When Antagonist with Checkbite option is checked, the Scanner add one Steps tothe Acquisition Workflow:

1. Checkbite acquisition

Checkbite acquisition


1. Total Model Acquisition with checkbite, 5 positions by default. A Finalize isrequired

2. At this point segmentation of the checkbite is needed to link each element to theproper tooth. After proper segmentation and linking the workflow proceeds in thestandard way
